Bosonic Nevanlinna Analytic Continuation [PDF]

Journal of the Physical Society of Japan, 2023
Analytical continuation (AC) connects theoretical calculations and experimentally measurable quantities. The recently proposed Nevanlinna AC method is capable of accurately reproducing the sharp features of spectral functions at high frequencies while ...

Interfacial Stresses for a Coated Irregularly Shaped Hole Embedded in an Infinite Solid under Point Heat Singularity

Mathematics, 2023
Particle-reinforced metals are being developed for advanced heat dissipation applications. However, an irregularly shaped void develops during eutectic solidification and enhances interfacial stress induced by visco-plastic deformation in temperature ...

Analytical continuation of imaginary axis data for optical conductivity [PDF]

, 2010
We compare different methods for performing analytical continuation of spectral data from the imaginary time or frequency axis to the real frequency axis for the optical conductivity .

Isomorphic classical molecular dynamics model for an excess electron in a supercritical fluid [PDF]

, 2008
Ring polymer molecular dynamics (RPMD) is used to directly simulate the dynamics of an excess electron in a supercritical fluid over a broad range of densities.

Matlab tool REGCONT2: effective source depth estimation by means of Tikhonov’s regularized downwards continuation of potential fields

Contributions to Geophysics and Geodesy, 2018
Transformation based on downward continuation of potential fields is an important tool in their interpretation – depths of shallowest important sources can be determined by means of stable downward continuation algorithms.

Lattice thermodynamics at finite chemical potential from analytical Continuation

Journal of Physics: Conference Series, 2018
An efficient way to study the QCD phase diagram at small finite density is to extrapolate thermodynamical observables from imaginary chemical potential. We present results for fluctuations of baryon number to order (μB/T)6.

How to Integrate Divergent Integrals: a Pure Numerical Approach to Complex Loop Calculations [PDF]

, 2000
Loop calculations involve the evaluation of divergent integrals. Usually [1] one computes them in a number of dimensions different than four where the integral is convergent and then one performs the analytical continuation and considers the Laurent ...

A numerical test of the topographic bias

Journal of Geodetic Science, 2018
In 1962 A. Bjerhammar introduced the method of analytical continuation in physical geodesy, implying that surface gravity anomalies are downward continued into the topographic masses down to an internal sphere (the Bjerhammar sphere).

The geoid or quasigeoid – which reference surface should be preferred for a national height system?

Journal of Geodetic Science, 2013
Most European states use M. S. Molodensky’s concept of normal heights for their height systems with a quasigeoid model as the reference surface, while the rest of the world rely on orthometric heights with the geoid as the zero-level.

Radar Cross Section Approach in Illusion Effects of Transformation Optics-Based Expander

Frontiers in Materials, 2022
In this paper, analytical calculation has been provided to show illusion perception in electromagnetics expander. For this end, a precise analytical solution has been done for a scattered wave from the expander including an object in the core medium ...
